Interestingly, the 4G growth has come at the cost of 3G data traffic, which has suffered a marginal decline in 2018. "By the end of 2018, there were more than five times as many 4G subscribers as there were 3G subscribers," the study said.

"Significant drop in data tariffs, coupled with the availability of economical 4G devices, led to the growth of the number of 4G subscribers by 137 percent. Further, the widespread migration of users from 3G to 4G devices also contributed to the increase in the consumption of 4G data traffic in the country," it said.

A rising number of people in the country are experiencing broadband for the first time on mobile and becoming increasingly aware of the vast opportunities of broadband in the country, said the study.

"This growth is led by the growing popularity of video streaming and video content in local languages on the various over-the-top (OTT) applications. The emergence of new media apps, like TikTok, has further led to an increase in video consumption. As the popularity of video streaming increases, telcos will need to provide better coverage and capacity in the rural sector as well," it said.

Sanjay Malik, Head of India market at Nokia, said the surge in broadband consumption is likely to continue in the next few years since the current broadband penetration is just 45 percent in the country.

"Further, the growth will be fuelled by 4G network expansions as telcos enhance the coverage and provide better network experience to the end consumer. Going forward, the service providers will need to expand the 4G network and evolve their network infrastructure to support 5G in near future," Malik said.
